Quantum Plates encapsulated within mIcro-pearls for 3D pixel matriX intEgrated in high performance dispLays – Q-PIXEL

Two technologies, QDEF (Samsung) and OLED (LG), are currently facing each other in the competitive market of high-tech TV displays. They both aim at continuously improving gamut, contrast, luminosity and reliability of displays while managing fabrication costs. In this context, the Q-PIXEL project proposes to develop an innovative and versatile approach that can be adapted to any type of displays: the electrostatic directed assembly on a transparent polymer film of a matrix of 3D pixels based on encapsulated fluorescent nano-objects. To achieve this, the Nextdot firm will work on a new production process of aluminum oxide micro-pearls encapsulating quantum plates with unrivaled photoluminescent quantum yield and stability. The LPCNO lab will focus on the 3D assembly of these micro-pearls in red/green pixels via nanoxerography by electrical microcontact printing. The LGC lab will carry out numerical simulations to optimize the geometrical and physico-chemical parameters driving the micro-pearl assembly.
